3. For the inhomogeneous differential equation x ′′ + 2x ′ + 10x = 100 cos(4t),
(a) Describe a system for which this differential equation would be an appropriate model.
(b) Find the general solution, x(t), to the equation.
(c) Does the general solution have the expected terms? What behavior do the terms describe?
(d) Find the specific solution that fits the initial conditions x(0) = 0 and x ′ (0) = 0.
(e) Plot the solution and discuss how you see the expected behaviors
